Ch 7 Flashcards
Driving forces of chem reactions
If it can happen it will!
Formation of solid
Formation of water
Formation of a gas
Transfer of electrons
The solid that forms is the
Precipitate
Strong electrolyte
Substance that completely breaks apart in a solution
Conduct electricity
When ionic compounds dissolve
The solution contains separated ions
Molecular equation
Shows complete formula of reactants and products
Complete ionic equation
Aqueous solutions are seperate into their ions
Solid stays solid
Net ionic equation vs spectator ions
Only the ions that react
Spectator ions are what don’t react
Acids always have start with
Common acids?
H or has COOH
HCl Hydrochloric acid
HN03 Nitric acid
H2SO4- Sulfuric Acid
CH3COOH/HC2H3O2 Acetic acid
Based start with
Common bases
OH
NaOH-Sodium hydroxide
KOH Potassium hydroxide
Ca(OH)2 Calcium Hydroxide
NH3 Ammonia
Arrhenius acid
Produces H+ ions when dissolved in water
100 HCL—> 100H +100Cl
Strong acid
Every molecule breaks apart
Complete dissociation
Arrhenius Base
Produces hydroxide/(OH-) when dissolved in water
Neutralization
When an acid base reaction reacts to form water and salt NaCl
Results in neutral solution
Oxidation reduction indicates transfer of
Elements by themselves have a net charge of
Usually a
Electrons
0
Metal and non metal
Non metals+Ox
C + O
Always redox!
